Indlela yokuklama nokwenza Ukushisa kwe-induction kanye nokucisha ama-inductors?

Ukucisha i-inductor kuyisici esibalulekile sokushisa esebenzisa umgomo we-eddy current ukuze ucime ingaphezulu lezingxenye futhi uqinise indawo. Kunezinhlobo eziningi zezingxenye zokushisa ezingaphezulu, futhi ukubunjwa kwazo kuhluke kakhulu. Ngakho-ke, ukuklama kwenzwa kuhlukile. Ngokuvamile, usayizi wenzwa ngokuyinhloko ucabangela ububanzi, ukuphakama, ukuma kwe-cross-sectional yekhoyili yokungeniswa, indlela yokupholisa amanzi kanye nomgodi wokufafaza, njll, kanye nomklamo wayo Umbono umi kanje.

1. Ububanzi benzwa

Ukuma kwe-inductor kunqunywa ngokuya ngephrofayili yangaphezulu yengxenye yokushisa. Kumele kube negebe elithile phakathi kwekhoyili yokungeniswa kanye nengxenye, futhi kufanele ifane yonke indawo.

Lapho ushisisa indilinga yangaphandle, ububanzi obungaphakathi benzwa Din=D0+2a; lapho ushisisa imbobo engaphakathi, ububanzi obungaphandle benzwa ethi Dout=D0-2a. Lapho i-D0 ingububanzi obungaphandle noma i-diameter yembobo engaphakathi yocezu lokusebenza, futhi a yigebe phakathi kwakho kokubili. Thatha u-1.5–3.5mm wezingxenye ze-shaft, 1.5–4.5mm wezingxenye zamagiya, kanye no-1～2mm wezingxenye zembobo engaphakathi. Uma i-medium frequency heat and quenching yenziwa, igebe lihluke kancane. Ngokuvamile, izingxenye ze-shaft zingu-2.5 ~ 3mm, kanti imbobo yangaphakathi ingu-2 ~ 3mm.

2. Ukuphakama kwenzwa

Ukuphakama kwe-inductor kunqunywa ngokuyinhloko ngokuya ngamandla P0 wemishini yokushisa, ububanzi D bomsebenzi wokusebenza kanye namandla athile anqunyiwe P:

(1) Ngokushisisa ngesikhathi esisodwa kwezingxenye ze-shaft emfushane, ukuze kuvinjwe ukushisisa ngokweqile kwamakhona abukhali, ukuphakama kwekhoyili yokungeniswa kufanele kube ngaphansi kobude bezingxenye.

(2) Lapho izingxenye ze-shaft ende zishiselwa futhi zipholiswa endaweni ngesikhathi esisodwa, ukuphakama kwekhoyili yokungeniswa kufinyelela izikhathi ezingu-1.05 kuya ku-1.2 ubude bendawo yokucisha.

(3) Uma ukuphakama kwekhoyili ye-single-turn induction iphezulu kakhulu, ingaphezulu le-workpiece lizoshiswa ngokungalingani. Izinga lokushisa eliphakathi liphakeme kakhulu kunezinga lokushisa ezinhlangothini zombili. Ukuphakama kwefrikhwensi, kusobala kakhulu, ngakho-ke kusetshenziswa amakhoyili wokujika kabili noma ama-multi-turn induction esikhundleni.

3. Umumo we-cross-sectional wekhoyili yokungeniswa

Ikhoyili yokungeniswa inezimo eziningi eziphambanayo, njengokuyindilinga, isikwele, unxande, uhlobo lwepuleti (ipayipi lamanzi okupholisa elishiselwe ngaphandle), njll. Uma indawo yokucisha ifana, ukugobela ikhoyili yokungeniswa kwesigaba esiphambanayo esingunxande yiyona ndlela engcono kakhulu. ukonga, futhi ungqimba oluvumela ukushisa lufana futhi luyindilinga. I-cross-section yimbi kakhulu, kodwa kulula ukugoba. Izinto ezikhethiwe ngokuvamile amashubhu ethusi noma amashubhu ethusi, ukujiya kodonga lwekhoyili yokungenisa imvamisa ephezulu ngu-0.5mm, kanti ikhoyili yokungeniswa kwefrikhwensi ephakathi ingu-1.5mm.

4. Indlela yokupholisa amanzi kanye nembobo yokufafaza

Uma kucatshangelwa ukuthi ukushisa kukhiqizwa ngenxa yokulahlekelwa kwamanje kwe-eddy, ingxenye ngayinye idinga ukupholiswa ngamanzi. Ipayipi lethusi lingapholiswa ngokuqondile ngamanzi. Ingxenye yokukhiqiza ipuleti yethusi ingenziwa isemishi noma ipayipi lethusi elishiselwe ngaphandle ukuze lenze umjikelezo wamanzi okupholisa; Ukushisa okuphezulu kwe-high-frequency okuqhubekayo noma kanyekanye kwamukela ukuzipholisa Ngesikhathi sokupholisa isifutho, ububanzi bembobo yesifutho samanzi sekhoyili yokungeniswa kuvame ukuba ngu-0.8～1.0mm, kanti ukushisa kwefrikhwensi okuphakathi kungu-1～2mm; i-engeli yembobo yomjovo wamanzi yekhoyili yokufaka yokushisisa okuqhubekayo kanye nokucisha ingu-35°～45°, futhi ibanga lembobo lingu-3～5mm. Ngesikhathi esifanayo, imigodi yokufudumeza nokucisha kufanele ihlelwe ngendlela ehlelekile, futhi ukuhlukana kwemigodi kufanele kuhlelwe ngokulinganayo. Ngokuvamile, indawo ephelele yezimbobo zokufafaza kufanele ibe ncane kunendawo yepayipi lokungena ukuze kuqinisekiswe ukuthi ingcindezi yesifutho nokucindezela kokungena kuhlangabezana nezidingo.

Kumele kuqashelwe ukuthi ukuze kuxazululwe umphumela we-annular wokushisa kwembobo yangaphakathi, amashidi e-ferrite (high-frequency harding) noma i-silicon steel (i-medium-frequency hardening) angaboshelwa kukhoyili yokungeniswa ukuze enze uzibuthe omise okwesango, futhi i-current iqhutshwa eduze kwegebe likazibuthe ( Ungqimba lwangaphandle lwekhoyili yokungeniswa) lugeleza. Ukuze kuvinjwe izingxenye okungafanele ziqiniswe ukuthi zingashisi, izindandatho zensimbi noma izinto ezinozibuthe ezithambile zingasetshenziswa ukwenza izihlangu kazibuthe eziyisiyingi esifushane. Ukwengeza, ngesikhathi sokushisa kokungeniswa, igebe phakathi kwekhoyili yokungeniswa eduze nekhona elicijile kufanele likhuliswe ngokufanelekile ukuze kuvinjelwe ukushisa kwendawo.
